8875 100% Acrylic Elastomeric Underseal - Black, 5/Gal

Stretch-Guard 8875 Underseal is a premium quality elastomeric coating that forms a flexible, durable, seamless membrane with 500% elongation. This membrane will stretch as the roof, or other substrate, expands and contracts due to temperature changes. Designed to resist ponding water, 88-75 Underseal is specified to be used to qualify for the Stretch-Guard Roof Coating System Warranty or other warranties that specify an elastomeric underseal.
